  • Publication number: 20230181857
    Abstract: A positive air way pressure mask includes a mask body having an inlet and an outlet, a nasal interface supported on the body, the nasal interface having air passages, with the nasal interface coupling a user's nose to the outlet of the continuous positive air way pressure mask body, and an air switch device having an input port, an output port, and a diversion port, with the input port receiving air from a continuous positive airway pressure machine and delivering the received air to the output port during an inhalation, and that switches the air from the positive airway pressure machine from the inlet to the diversion port to expel diverted air to ambient during an exhalation.

  • Patent number: 11456681
    Abstract: Described is an electrically actuated, pneumatic driven motor. The pneumatic driven motor includes a body having first and second surfaces, the body having a chamber defined by an interior wall, a displacement cavity, and a passage that fluidly couples the displacement cavity to the chamber, a bleeder port and a bleeder port passage that fluidly couples the bleeder port to the chamber, a valve disposed in the passage between the displacement cavity and the chamber, an annular pushrod mechanism coupled to the valve, the annular pushrod mechanism having a pair of pawls that protrude from an inner surface of the annular pushrod mechanism, an axle disposed in the chamber; and a motor gear disposed about the axle, the motor gear having a plurality of teeth that selectively engage with the pawls on the pushrod mechanism according to displacement of the annular pushrod mechanism.

  • Patent number: 11359619
    Abstract: Disclosed are techniques such as roll to roll processing to produce inlet valves for controlling entry of fluid into a compartment of a device. The valve includes a body having a compartment and an inlet into the compartment, with the inlet being bifurcated by a pair of spaced wall portions of the body that form a confining region and which pair of spaced wall portions together with wall portions of the body provide a pair of spaced inlet portions into the compartment and a valve member having a first portion that is position-able within a portion of the compartment, an intermediate portion, and a second portion coupled to the first portion by the intermediate portion, with the second portion position-able within the confining region and with the second portion having an obstruction portion.

  • Patent number: 11296619
    Abstract: Disclosed is a force transfer device that includes a first body that has a first body frame that defines a first chamber and at least one gear element. The gear element has a central gear element region. A first membrane is affixed to a surface of the first body frame, the membrane covering the chamber and having an annular aperture enclosing a central region of the membrane that is affixed to the central gear element region of the gear element. The disclosed force transfer device can be axle or shaft based. Also disclosed in a micro electrostatic motor that includes a motor body having a first and a second face, the motor body defining a chamber and a rotor having a central region. A membrane is disposed over the first face of the motor body, the membrane supporting a pair of spaced electrodes that are electrically isolated by a gap, the membrane having an annular aperture that defines a central region of the membrane that is coupled to the central region of the rotor.

  • Patent number: 11245344
    Abstract: Disclosed is a micro electrostatic motor that includes a body having a first and a second face and having a chamber. A first membrane is disposed over the first face of the body and a rotatable disk is disposed in the circular chamber about a member. The disk is disposed in the circular chamber and is free to rotate about the member. The disk has on a first surface thereof a set of three mutually electrically isolated electrodes, with each of the electrodes having a tab portion and being electrically isolated from the member. A second membrane is disposed over the second face of the body and a pair of spaced electrodes are provided on portions of the second membrane, with the pair of spaced electrodes being isolated by a gap between the pair of electrodes. A cylindrical shaped member is disposed in the chamber electrically isolated from the three mutually electrically isolated electrodes on the disc.
